Abstract

A triangular, sharp projection is formed in the surface of a key handle, the projection being directed into the interior of a key ring opening formed therein. This key ring projection includes edge recesses formed proximate the base thereof thereby providing a shape forcing the segments of a collapsed helical key ring apart, the recesses then maintaining the ring segments separated for insertion or removal of additional keys. In an alternative implementation the similar key ring separation projection may be formed on articles other than keys that can thus be carried on the key ring for convenience in key removal.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A planar sheet structure for separating the collapsed coils of a key ring, comprising: a generally triangular structure projection including an apex defined by the intersection of two arcuate concave sides each extending from said apex to a corresponding one of two opposing recesses separated by a base connection of a key ring carried object, each said recess being conformed to receive a coil of said key ring; and   a peripheral edge strip surrounding said structural projection, said edge strip including a passageway being defined by two opposed outwardly bent edge members separated by a dimension greater than the sectional dimension of said key ring.
